Background / History

Suzune enters Advanced Nurturing High School as a Class D student. She regards her placement as a mistake and becomes determined to advance to Class A, initially believing poor-performing classmates are holding her back. Her ambition is closely tied to her older brother, Manabu Horikita, the Student Council President and a third-year Class A leader whose example she has tried to follow. 22 24 29

Her first encounter with Keima Katsuragi is hostile: after noticing him staring on the bus, her affection reading falls from 0% to -3% when their eyes meet. She is further unsettled by his blunt compliment and apparent indifference toward her. 2 3 4

Suzune earns a perfect score on Sae Chabashira's unannounced quiz, though the final question gives her difficulty. Keima's equally perfect score—achieved while he was playing games—leads her to question him and begin recognizing his exceptional observation and memory. 7 8

After learning that class standings can change, Suzune begins pursuing Class D's academic improvement. Her first plan is to gather the lowest-scoring students for remedial lessons, but Keima criticizes the approach as insulting and counterproductive. Their dispute becomes a wager between their respective study groups. 22 24

Keima's confrontation with Manabu forces Suzune to reconsider her assumptions about her brother and herself. Although embarrassed by Keima revealing the game cartridge she bought for him, she realizes he defended her potential before Manabu. She thanks him afterward and becomes more open to examining her own flaws. 30 31 32

Appearance

Suzune is described as a strikingly beautiful girl with an expressionless, cold presence. Her appearance is refined enough to draw immediate attention, though her demeanor keeps others at a distance. 2

• Long black hair reaching her waist. 2
• A ribbon and a long braid on the right side of her hair. 2
• Fox-like eyes. 2
• Usually maintains a stern or unreadable expression. 2 3

Personality

Suzune is proud, highly self-reliant, and initially antisocial. She dislikes compromising for others—even refusing to give up her bus seat—and speaks sharply when irritated. Her fixation on reaching Class A leads her to see classmates with weaker grades or poor behavior as burdens. 3 24

Despite this harshness, she is earnest about self-improvement and class advancement. She honors agreements even when doing so embarrasses her, such as purchasing Keima a game after promising to do so. 28 29 30

Following her conversations with Keima and Manabu, Suzune begins softening her attitude. She greets Keima voluntarily, her usual emotional distance diminishes, and she starts reconsidering whether she has truly understood the people around her. 31 32 33

Abilities & Skills

Relationships

• Manabu Horikita — Her older brother and the standard she has tried to emulate. His harsh treatment and insistence that she find her own path are central to her insecurity over Class D. 29 30 31

Story Role / Major Arcs

Early Encounters with Keima

Suzune begins as Keima's aloof seatmate and reacts negatively to his direct attention. His deductions about the school's surveillance and rating system nevertheless earn her reluctant respect. 2 3 4 6

Class D Academic Improvement

After discovering the significance of class rankings, Suzune resolves to bring Class D toward Class A through academic improvement. Her disagreement with Keima over how to motivate weaker students becomes a formal competition between study groups. 22 23 24 25

The Game-Cartridge Promise

To secure Keima's cooperation, Suzune agrees to buy him a game. She follows through despite intense embarrassment when the store clerk announces its explicit title in front of Airi and Hiyori. 28 29 30

Reassessment of Manabu and Herself

Suzune meets Manabu seeking recognition, only for Keima to intervene and argue that her flaws do not eliminate her potential to grow. The encounter loosens her misunderstanding of Manabu's intentions and begins changing her relationship with Keima. 30 31 32

Trivia

• Keima's card system initially lists Suzune's affection at 0%, which drops to -3% after their first eye contact. 2
• Keima repeatedly compares her outwardly cold behavior to a “tsundere” character type, a label Suzune strongly rejects. 8 24
• Suzune enjoys reading in her spare time; Keima identifies her reading habits through library checkout records and a glimpse of her book. 29
• Although she considers games detrimental to studying, she becomes curious enough to ask Keima about their appeal after buying him one. 29 32
